Big Bone Lick State Historic Site has been named by the U.S. Secretary of the Interior as a National Natural Landmark.  
The park is significant for its combination of salt springs and late Pleistocene bone beds.  Ancient creatures like  the mammoth, mastodon, ground sloth and bison once roamed through  mineral  springs  and  swamps.  
The site is recognized as the birthplace of American vertebrate paleontology  for  its  significant  role  in  the  development of scientific thought regarding extinction and the relationship of geology and paleontology the world over.
